DOOR-CHECK.

SPECIFICATION forming part of Letters Patent No. 432,867, dated July 22,1890..

Application filed January 27, 1890. Serial No. 338,169. (No model.)

To all whom it may concern:

Be it known that we, CHARLES W. FISHEL and FRANK S. HOTCHKISS, ofOarbondale, in the county of Garfield and State of Colorado, haveinvented a new and Improved Door- Check, of which the following is afull, clear, and exact description.

Ourinvention is animprovementin thatclass of door-holders or so-calleddoor-checks whose main feature is a springcatch adapt-ed to receive andfirmly clasp a knob or projection (which is in practice attached to thedoor.) In our device the spring-catch is inclosed in and protected by adetachable barrel or tube that is applied (by means of a screw-joint) tothe part having a screw for attaching it to a wall, as herein described.

Reference is to be had to the accompanying drawi'ngs,for1nin g a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures. I

Figure 1 is a perspective View of the im' provement as applied. Fig. 2is an enlarged side elevation of the same with parts in section; andFig. 3 is a sectional plan view of the same on the line as a; of Fig. 2.

The improved base, knob, and door-holder A is provided with a knob B,adapted to be secured to the door 0, and provided with a rounded offsetD, on which is formed a shoulder E, from which projects a screw F,adapted to screw in the door until the ofiset E abuts against the door.The rounded part D of the knob 13 is adapted to be engaged by aspringcatch G, made of two spring-plates G, each having at its free enda curved part G similar in shape to the outer surface of the roundedpart of the knob 13.

The ends of the spring-plates G are secured to a bar H, having its outerend formed into a fork I, between which is journaled a plate J by meansof a bolt K, held in the fork I. The plate J is provided with a flangeJ, from which extends centrally a screw J adapted to screw into thebase-board of the wall L until the flange J abuts against saidbase-board. (See Fig. 2.) The plate J is secured to the base-board L inthe usual manner, so that it stands horizontally, while the pivot pin orbolt K extends vertically, to permit of swinging the catch G into anydesired angle in relation to the base-board L.

On the bar H, near the fork I, is formed a thread H, adapted to beengaged by an interior thread formed on one end of a barrel N, adaptedto cover up the springcatch G, and open at its outer end to permit theready entrance of the rounded part D of the knob B. The barrel Nprevents to a great extent dust from settling on the spring-catch G, andalso prevents the latter from being injured.

The door-holder is used as follows: The spring-catch G is secured to thebase-board L by the plate J screwing in the base-board L, and then theknob is screwed to the door O near its lower outer end, so that when thedoor swings open the knob B is in position to engage the bent parts G ofthe springplates G, as illustrated in Figs. 2 and 3. When this takesplace, the said spring-plates G, by their rounded parts G pressing onthe rounded part D of the knob B, hold and lock the door in an openposition until the operator exerts considerable pressure on the door inorder to disengage the rounded part D from the spring-catch G.

It will be seen that as the spring-catch G is articulated itcan becurved into any desired position, so as to engage the knob 13 at alltimes.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is-

The improved door-holder consisting of the forked bar H, having thecylindrical threaded portion H, the spring-catch plates G, secured tosaid bar, and the internally-threaded barrel N, adapted to inclose saidcatches and to' screw on the bar H, and the flanged plate J, pivoted tothe latter and having a centrally: projecting screw, as shown anddescribed.
